(Nanowerk Spotlight) Nanofluidic channels feature a unique unipolar ionic transport when properly designed and constructed. Recent research in nanofluidics has adopted reconstructed layered ...

Part of Biology (Single Science) Living together - Food and ecosystems Active transport is a process that moves molecules against a concentration gradient. The process requires energy. For plants to ...

The alternative to active transport is passive transport, which uses kinetic energy only to move the molecules. Passive transport can only move molecules from a region of higher concentration to lower ...
